Brainlest awardhow does smoking and arterial plaques increase the risk of hypertension? (2 points) select one: a. both increase blood volume. b. both decrease blood volume. c. both expand the diameter of the blood vessels. d. both constrict the diameter of the blood vessels.

Option D

Explanation:

Smoking and arterial plaques increases the risk of hypertension as both of them constrict the diameter of the blood vessels that produces extra pressure on the walls of the blood vessels.

There is a substance called fibrin that is found in the blood vessels that allows the smooth flow of blood. But smoking and arterial plaques hinders the production of fibrin and without fibrin, the fatty acids and lipids starts to deposit on the walls of the blood vessels resulting in extra pressure on walls of blood vessel.

This decreases the diameter of blood flow and as a result of this the pressure increases leading to hypertension.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
